Application Performance Monitoring (APM) is a technical process that involves using software tools to collect and analyze data about the performance of an application in order to identify and resolve issues that may impact user experience. APM typically involves the instrumentation of an application’s code to capture data about key performance metrics, such as response time, error rates, and resource utilization.
This data is then collected, analyzed, and displayed using dashboards and visualizations that provide real-time insight into the performance of the application. APM tools may also provide advanced diagnostic capabilities that allow developers to trace individual transactions and troubleshoot issues by correlating performance data with application code changes.
